France officially marked the two-year remembrance of the Charlie Hebdo terror attack.
On Jan. 7, 2015, a pair of gunmen burst into the headquarters of the French satirical magazine and killed 12 and wounded 11 others. Five others were killed in Paris that day, four by a shooter allied with the Hebdo killers.
The Hebdo gunmen, who were brothers, were later killed by police in a shootout. The magazine has a history of irreverent humor, including poking fun at the Prophet Muhammad.
